Around 8:15 p.m. a transmission issue caused residents on the southern part of town to lose power.

A spokesperson from Alliant Energy said several lightning strikes over the last couple of years blew the insulation in a sub-station. Crews had to wait for a journeyman from Mason City to fix it.

They said this type of sub-station requires them to wear a full protective suit, which is rare, most of the time protective rubber gloves will do, and the closest available person who is trained to do that was in Mason City.
